Cristiano Ronaldo has taken to Twitter to deny reports he has extended his contract with Real Madrid.

Despite the assurances of Real Madrid president Florentino Perez, The Portuguese international has found himself linked with a number of moves away from the Bernabeu, including an emotional return to Manchester United.

Perez was adamant that Ronaldo is destined to remain at Real for many years to come earlier this week, telling Marca that the player is as committed as ever to the Los Blancos cause.

But in an unprecedented move by the 28-year-old, Ronaldo has dispelled the suggestion that a new deal was done, tweeting, "All the news about my renewal with Real Madrid are false."

Ronaldo made his world record £80m move to the Bernabeu from Manchester United in 2009, but suggestions of discontent in the Spanish capital refused to go away throughout the second half of last season.

Both Paris Saint-Germain and Monaco have been linked with astronomical bids for the forward; with both clubs seemingly well within their means to tempt the Portuguese international away. A return to Old Trafford remains a tantalising prospect for United fans, but whether the Premier League champions would be able to match the financial clout of the Ligue 1 duo remains to be seen.

Despite the fact that the 2009 Ballon D'or winner is contracted to Real until 2015, Perez has seemed eager to address Ronaldo's future as soon as possible in efforts to dispel speculation.

"I am going to be clear as possible. My aim, Cristiano's aim, and the aim of all Real Madrid fans is that he carries on playing here for many years to come," Perez told Marca.

"When so many people want the same thing then it usually turns out to be the case, I myself and Real Madrid both want that.

"The player, Cristiano Ronaldo, also wants that. Without a shadow of a doubt, that is what Cristiano wants too."

But Ronaldo's latest comment, which he also shared with his 58 million fans on Facebook, suggests that things are not as straight forward as Perez has indicated.
